The phases proportions analysis indicates the predominance of HCP structures with 97% at 4 A/dm2.
In support of these observations, the earlier electron diffraction patterns obtained in conjunction with TEM of calcium granules and the purported NB showed a predominance of polycrystalline structures compatible with the presence of amorphous aggregates undergoing varying degrees of crystallization [2], [3].
Microscope observations in the reflecting mode confirmed this conclusion by showing a predominance of amorphous structures.
As additional controls, commercial compounds of CaCO3 (Fig. 10J), Ca3(PO4)2 (Fig. 10K), and HAP (Fig. 10L) were similarly incubated in DMEM prior to their being processed for TEM (only data for 1 hour incubation shown here; longer, overnight incubations resulted in a predominance of crystalline, monolithic structures).
In IPCs with relatively small patches, the P(α xy ) curves deviate weakly from a homogeneous distribution; however, the presence of two smooth peaks, one at α xy ≈ 0 the other at α xy ≈ 60°, indicates a predominance of hexagonal ring structures (see also Figure 3 ).
In its FTIR spectrum we observe multiple small absorbance peaks not corresponding to a predominance of any specific structure.
The specific surface of WDC is less than the one of AC in Ag, Elcg and Btg1 horizons by 64, 95 and 28 m2/g, respectively, because of the predominance of minerals with rigid structures in its composition.
A hallmark of highly migratory cells is diminished focal adhesions and stress fibers and the predominance of the early focal contact structures.
The secondary structure content of rMEHB estimated from spectra according to the Raussens et al. method [ 25] shows predominance of unordered and β-sheet structures in both pH 7.0 and 8.0 at 25°C (Table 2).
Based on their structures, cationic AMPs are divided into four major classes: α-helical peptides, β-sheet peptides which are stabilized by up to three disulfide bridges, loop structures containing only one disulfide bridge, and extended structures with a predominance of one or more amino acids [ 3- 7].
